ADZI'USTABLE FIX'1URE STRAE.

Application filec1 I/.Eafch lv1y invention rclates to tl1oss de/vices Which are particularly adnpted 10r use in insualling electrical fixtures zmcl relz1ies more particularly 150 a, fixture strap by means 01 which a, fixture supporting stucl nmy be se curecl in position.

111 a grsat number f elec-tricslinstallations, especially where lt is founcl desirable employ a ceiling 01 Wall 1102;, it is tl1e 10 usual pmetice to mount the electriaal fixture upon a sind projecting frozn tl1e Wall 01' ceiling, as ths esse may be. That part 01 tl1e fixture which is n0t omamental ancl Which serves primarily as tl1e fixture sup port is coverecl by an ornamsntal plate hav-' ing a centrally clisposscl aperture through Which tl1e fixture stud projects. '1he sind er nipple, Which is hollow t0 permit passage thel'ethrough 019 the electric wires, is in mosl cases mounecl upon a stmp which in tu1n is supportecl upon the eclges 013 tl1e W2Lll 01' csiling box. 111 is t-he usualpract-ice 10 provide this strap with a fixeclly locarecl threacled -aperture, usually centrally locatecl, in which the sind is thrsacloclly supportecl. 1 lmve founcl filmt in a great number 01 instances Constructional cletails of the Walls und ceilings make it imperative that tl1e 10022 l1e locat 'ecl in a certain place. Das t0 bl1e l21ct that 1he sind securing aperure is fixed with respect to tl1e b0x it tl1en bccomes impossible to properly und. with exa ctitucle locat-o the elsctrlcal fixture so fr ns symmetry W11l1 respect t-0 other zmcl neigllborlng fixtures is concerned. Also, there a1s instances when tl1e hole in wl1ich the box is t0 be accomm-oclatecl l1as been incorrectly located in the Wall O1 ceiling with tlm result filmt eithe1 ths hole muSt be fillecl in and a, new one macl'e 01 else the fixture mountecl in ihemct anrl undeslrecl position.

It is among the gen-eral 0lojemts 01 my invenon to provicle a fixtmrs stmp which has an adjustable apart-um such that tl1e fixture supporting; stucl whlch is recsived th:ls aperture is macle inclepenclent 01" tl1e locati0n 0f the box within compsmtively wicle .li1nits Wil-l1 the result that the l181(510f016 existing clefects ancl objehztionabls .feamres a1e entirsly eliminahecl. A. fm-ther object is ehe rovision 01 n fixture shap wl1ich is aclzipted 10 bs 0&1I'19C1 by ths c0nduit lo0x in tl1e usual .mzlnner bulv having an sdjnstsbly 1nountecl member which is threacledly rereivecl the main feaizure supporting element. A still further 0lojecb is the provision of a fix ture 10 1926. -Serial N0. 93,556.

strap which permits thelocation 0f the elec 'trical fixture irrespective 0f the location 015 the Wall 1- ceiling b0x. A still fu1ther object is lhe provision 01 in acljustable Wal]. 01 seiling fixture strap Which is compact, strong, zmcl excsecljngly simple ancl cheap t0 manufactufe. Other objects Will appear more fully herein1fter.

My inventibn consists snbstantially in the construction, co1nbinationlocati0n ancl relative arrangcement of parts, all as Will bemo-re fully hereinafter se forth, as shown in tl1e accompanying drawings, und finally pointed out in the appenclecl claims.
